VIEW CASE STUDY

Our SML 1200 SD Oil and Gas platform is a standard build, concluded for the following application profile which is based on an actual build. It is not regarded as exhaustive, and is provided as a means of providing prospective clients with a practical case study to work from.


ORIGINAL END USER REQUIREMENTS

We were approached by a Civils contracting company based in Johannesburg to design and construct a vessel with maximum deck space to be used for civil works, dredging and piling works on a project in the East London Harbour area, South Africa. The vessel had to be capable of being easily deployed to any other site once the contract had been concluded.

The vessel was required to carry at least 5 tons of deck cargo with only a simple T-top shade awning over the vessels; instrumentation console being required.

A knuckle boom crane base along with below deck structural support was required to be built into the vessel for possible future fitment. 

4-point anchoring system with manual mooring winches and suitable mud holding anchors to be supplied.

Heavy duty lash-down points built into the deck for securing equipment and cargo were also stipulated as requirements.

SAMSA Category D 8 crew safety certification was required.
