From Maassluis and Hoek van Holland to the anchorages off the Dutch and Belgian coast, Sima Charters use fast crew tender vessels (CTV) to transport up to 12 passengers. Crew, pilots, surveyors, technicians as well as supplies and spare parts: we are ready to transport them 24 hours a day, 7 days a week. Our response time is very short, usually departure ... Moreis within the hour.

An offshore wind farm off the English coast, a dredging project in Dubai or a coastline survey in Egypt: they all benefit from the reliable and efficient CTV services Sima Charters provides. Our vessels are well equipped and our crews trained and motivated to deliver time and time again.

Sima Charters and IGL offer full survey solutions combined with crew service possibilities. The high spec CTVs from the Sima Charters fleet are ready to act as both. Due to clever designs, these vessels can be operated for survey straight after the designated passengers are safely transferred to their offshore location.
