Repair and Conversion

A New Lease of Life

ST Marine is a leader and specialist in sophisticated repair services that keep sea-faring vessels in shape. We are also experienced in converting existing ships for new uses, repurposing them for new missions and objectives. Our proven expertise in the design and construction of customised vessels gives us an edge in providing technically complex repairs and upgrades.

Besides maintaining and retrofitting naval vessels, we also provide upgrading, mid-life conversions and servicing to improve its lifespan.

In the commercial sector, our work includes the modification and jumboisation for various ships. We have conducted high value-added repairs on vessels such as seismic, dredgers, chemical tanker and offshore vessels.

Considering the current market climate where the offshore industry hits a downturn, we are obtaining new capabilities to enter segments that are growing i.e. medium size LNG vessels and FSRUs. We are also actively involved in working with prospective vessel owners to carry out unconventional conversion projects like FPPs and FUVs.
