The International Jack up Barge Operators Association (IJUBOA) is a maritime company based out of United Kingdom. Formed in 2008 with a mission to set, sustain and promote standards for the safe and effective operation of self elevating platforms throughout the world, IJUBOA has three strategic goals: ... More

To promote a safe industry – safe for its people, for the environment and for society at large

To promote a learning industry – with the skilled and professional workforce essential for the safe and efficient operation of jack up barges

To promote a well run industry – responsive to the needs of its customers and committed to continuous improvement.
Originally, we started out as the British Geotechnical Society, formed in 1949 as an unincorporated association. We became a registered charity by statutes adopted in December 1981 and amended in January 1997. We became the British Geotechnical Association (BGA) by statutes adopted in June 2000 and amended in June 2005 and June 2011. The charity number ... Moreis 284131.

We organise regular technical discussion meetings about a range of topics relevant to ground engineering. These include regular events such as the Rankine Lecture, the Touring Lecture (which travels around the UK regions), the Geotechnique Lecture, and the Geotechnical Engineering Lecture. We work closely with other learned societies and hold regular joint meetings and events with the Engineering Group of the Geological Society, the British Tunnelling Society, the International Geosynthetics Society, and the Offshore Engineering Society.

As well as awarding the role of the speaker for the prestigious Rankine Lecture, we periodically award the Skempton Medal and the BGA Medal for contributions to geotechnical engineering and associated publications. The Fleming Award is for team working and innovation in construction. Young engineers are eligible to enter the Cooling Prize and we now also award an annual prize for the best MSc dissertation in a ground engineering related subject.

The BGA is one of the most vibrant and active societies in engineering. Why not embed yourself within our community by joining the BGA. We offer special rates for students and the retired. Corporate membership is also available.
The Association of Geotechnical and Geoenvironmental Specialists (AGS) is a non-profit making trade association established to improve the profile and quality of geotechnical and geoenvironmental engineering. The membership comprises UK organisations and individuals having a common interest in the business of site investigation, geotechnics, geoenvironmental ...

Our Mission 

promote and enhance the quality of professional practice in geotechnical and geoenvironmental engineering

facilitate close liaison between all geotechnical and geoenvironmental organisations

champion and represent the geotechnical and geoenvironmental industry

represent and uphold Member’s interests in commercial and professional matters

agree and publish guidelines on good practice and on ethical and professional matters

encourage quality management systems in geotechnical and geoenvironmental work

assist and influence decision making within Client organisations

In furtherance of these objectives, meetings and seminars are held each year in various parts of the country and a series of publications have been issued. In addition, a Newsletter is distributed six times a year to key individuals within organisations across all sectors of the industry to publicise the work and progress of the AGS and its working parties and to present informed articles and commentaries on topical issues or events.
Equipment & Solutions
CPT Equipment
The WISON-APB-Classic is capable of performing cone penetration tests (CPTs) and taking soil samples at depths up to 550 m (water depth + drilling depth). It requires a drill string with an inner diameter of at least 101.6 mm (4") and a drill tower clearance of 11 m. The WISON-APB 100 version has a pushing capacity of 100kN and is capable to performing ... Moretests with a 1m and 3m stroke length. The WISON-APB 100 comes with an electric winch that is self-tensioning for heave compensation. The winch allows the tool to travel at a maximum speed of 2 m/s inside the drill string.

Key Features

Proven wireline CPT system with a pushing force of 100kN

Water depth + drilling depth up to 550m

CPT stroke of 1m or 3m

Suitable for 5cm² and 10cm² Icones (up to 100MPa tip resistance)

Case Studies
The safe positioning of production platform depends on balanced penetration of legs until a stable founding depth has been achieved. The very soft clays in the Gulf of Guinea can result in leg penetration reaching between 40m and 50m - the practical limit of many production platforms. At the mouth of the River Congo however, highly variable ground ... Moreconditions lead to unpredictable soil strengths and hence leg penetrations.

The client was concerned about achieving leg stability at depth and engaged Lankelma to provide Leg Penetration Assessment (LPA) services, comprising fieldwork and reporting, to enable location approval and warranty surveyor certification.

To date, four campaigns have been carried out. Our initial team, plus our Heli/hand portable drilling and CPT equipment, were mobilised within two weeks to address the most urgent concerns.

Clear technical, operational and safety procedures were developed with the client before work began, to identify risks. Briefing documents managed the Lankelma/client operational safety interface and key emergency protocols were agreed.

The Lankelma team grew to 15, including field laboratory and geotechnical analysts, providing realtime preliminary assessments.

Work was carried out 24/7 using third party vessels and rigs, in water depths up to 25m, with testing to 80m. Each campaign satisfied warranty officers of the viability of the rig location and operation.
Lankelma carried out multi-disciplinary geotechnical and geophysical investigations for a jetty extension, construction of a new bauxite-handling jetty and dredging of an approach channel at a Container Terminal in Guinea. The jetty was being extended by 500m and a new berthing pocket dredged, to allow barges to offload bauxite. The new 500m long Jetty ... Moreis due to be built to the south of the existing Jetty. Investigations also covered the 17km approach channel being dredged in the estuary.

Lankelma used its Combifloat C5 Jack-Up Platform "Sandpiper" to carry out cone penetration tests (CPTs) up to 23m deep and drill geotechnical boreholes to 50m through the underlying clays, silts, gravels, laterites and into the underlying sandstone.

Along with offshore piston sampling and thin-wall push sampling, the investigation included nearshore CPT and drilling, geotechnical laboratory testing, data interpretation and correlation, and geotechnical reporting.

Lankelma's former sister companies – Gardline Geosurvey and Alpine Ocean Seismic Surveys – undertook bathymetric and geophysical surveys, metocean surveys, tide gauge installation and monitoring. Vibrocores were also carried out using a client-chartered vessel along the approach channel to ground truth the results of the geophysical survey.

The team had to overcome major logistical and health challenges (including the outbreak of the Ebola Virus) and maintained good communications and relations with the client and its engineering consultant throughout.

Shallow Water Deep Trouble II – What a Difference a Decade Makes. EEEGR Marine SIG are pleased to co-host a prestigious technical meeting in partnership with the Society for Underwater Technology (SUT) at Norwich City Football Club, UK. Site investigations in the nearshore and shallow water can present unique challenges, with potentially significant ... Morevariations in ground conditions, bathymetry and environmental parameters within individual development sites and construction
time scales. Investigations may be for a range of purposes – from providing baseline environmental information and site characterisation through to informing engineering decisions and infrastructure siting.

Since the first 'Shallow Water … Deep Trouble' meeting was held in 2005 in Norwich, UK, there have been major advances in data acquisition technology, analytical techniques, data processing and visualisation, that have improved site investigation practice and advanced our understanding of the shallow water zone. This meeting will report on a range of approaches to shallow water site investigation, as well as providing an update on recent methodological advances, that allow for successful site investigations in a challenging environment. The meeting will be of interest to all those working in nearshore and shallow waters – with contributions from industry, academia, contractors and consultants.
