SURVEY VESSELS SIGNIFICANT BREAKTHROUGH


CTruk Group has made a significant breakthrough into the survey vessel market with the delivery of a first-of-class boat to the Port of London Authority (PLA).


The 17m Maplin builds on the company’s pedigree as a leading supplier of composite catamaran workboats to the offshore windfarm support market and the company has incorporated many of the lessons learned from building these vessels (WFSVs) into its survey boat design.


VESSEL SPECIFICATION Maplin, which was built at CTruk’s Colchester facility, will serve the PLA in Thames river and estuarial waters where its flexibility will prove invaluable, providing the advantages of a catamaran hull form that offers considerable working deck space and a composite structure that will significantly reduce maintenance costs. The boat has deck space of over 30 square metres and displaces 28 tonnes.


PLA Port Hydrographer John Pinder explained: “We have a wide ranging fleet which enables us to work


on the river or out into the North Sea and nowadays we are doing more and more environmental and geophysical case management work. With things like acoustic current profiling, parametric sonar or magnetometers, we need to deploy more equipment.


"We intend operating Maplin in the river but also out in the estuary and I envisage we will experiment with using the boat to work longer days, which will enable us to exploit a wider weather window."


feature is a low profile wheelhouse and retractable mast, specially designed for the boat to gain access under the low bridges of the Thames.

“Although we have been getting excellent results with the multi-beam sonar for a number of years, the increased working deck space of the catamaran allows us this greater flexibility. Maplin has a high freeboard and good working areas inside and out. Indeed, the quality of the fit out has been to a very high standard."


STABILITY


The vessel is based on the CTruk MPC19 catamaran which has been proven to have good stability and seakeeping characteristics. The stability will enhance survey capability, allowing more effective use of the multi-beam deployable sonar unit built into the hull, while another special
