Intervention Engineering (IE) rhas successfully installed  a number of FPSO Seachest Blanks on-station using asset deployed mini-ROVs. The largest blanks currently installed measure 1450 × 950mm and weigh 195kg.

Operating from on-board the FPSO during normal operations, IE’s three man team conducts cleaning and measurement of the intakes and surrounds before deploying and installing blanks. IE’s innovative installation solutions utilise the existing vessel Seachest Blanks,our  installation aids enabling accurate pull-in, alignment and positive locking of the blanks.

Overboard Pluging is now commonplace, with the security of double seals
