Surf Operations

Most offshore field development projects require Subsea Umbilicals, Risers & Flowlines (SURF) scopes of work as part of development.
IOC provides a range of Subsea operation services to include SURF (subsea umbilical, riser and flexible) installation services include:

  • Umbilical, riser and flexible installation, termination and hook-up
  • Installation of PLEMs, PLETs, jumpers, manifolds, flying leads
  • ROV services
  • Subsea inspection maintenance and repair services
  • Subsea salvage services
  • Deployment: Pull-in Equipment / Systems

Umbilicals connect from the surface facility to the subsea development through an Umbilical Termination Structure (UTS). From the UTS, umbilical services are transported to the various subsea equipment located on the field. Many times umbilical services are “flown” from apparatus to apparatus via a flying lead, which is similar to the common extension cord.

Risers transport produced hydrocarbons, as well as production materials, such as injection fluids, control fluids and gas lift. Usually insulated to withstand seafloor temperatures, risers can be either rigid or flexible.

risers

Subsea flowlines are the subsea pipes used to connect a manifold to the surface facility in order to convey fluids to or from the host. They are arteries of the offshore production system, used to transport production, well testing, water injection, gas lift or gas injection. Their integrities play a central role in maintaining sustained production.
