Multi-Purpose Support Vessels (MPSV's), also known as Light Construction Vessels, are designed with flexibility and versatility in mind. They are capable of performing a range of activities including: supply duties, lifting operations, ROV and survey activities, platform and SPM maintenance, diving, light well intervention and accommodation support.
To ensure flexibility MPSV's may feature: a dynamic positioning system, heli-deck, cranes, a large open deck area, tank capacity for liquids, large accommodation and walk to work gangway systems.
MPSV's can be broadly split into high-spec and low-spec. Low-spec MPSV's operate in waters of less than 150m and are typically smaller and with lower crane capacity. High-spec MPSV's feature much of the latest technologies and are capable of handling larger loads at greater depths and greater environmental demands. Typically high-spec MPSV's operate in deepwaters or where the scope requires higher capabilities (large crane capacity, DP-2/3, ROV, accomodation etc)
