Case Studies

GNLQ Terminal is a grass-roots LNG receiving terminal located at Quintero Bay, approximately 160 km north-west of Santiago, Chile. LNG carriers are unloaded at the terminal where the LNG is stored and regasified.

The BBL (Bacton-Bagzand line) plant, operating on the Shell Bacton Gas Terminal, lands sales specification gas from a compression station in Anna Paulowna in the Netherlands.
BBL Pipeline capacity is sold to shippers on the open market, with trades setting the amount of gas transfer required within the next Gas Day (Nomination). To ensure that the Nomination is acceptable based upon plant capacity, an End-of-Day (EOD) system sits within the control logic and accepts or rejects nominations.

Colbún S.A. and AES Gener required the supply and operation of an offshore LNG Regasification terminal at Oxiquim Port, Quintero Bay, Chile. The terminal was to utilise an FSRU to store LNG and export Natural Gas via a pipeline to the local network when required.

OSL were requested to carry out process design activities relating to a proposal to retrofit an LNG unloading contingency system to an existing facility at GNL Quintero in Chile.

The BP SGA team carried out LOPA assessments on their existing plant at the Dimlington onshore terminal. A team from OSL was asked to provide process engineering support to the BP team to carry out LOPA studies on parts of the plant and to provide process engineering solutions to some of the actions raised.

Installation of the world’s first 100 barg rated ship to shore HP gas loading arm and downstream gas metering and treatment systems which were subsequently connected to the national grid via a buried delivery pipeline.

OSL undertook a study, for the client, with the aim of investigating ways of rationalising their Southern North Sea gas production infrastructure. The objective of the study was to look at ways of reducing operational expenditure and increase returns, with declining field reserves.

A Liquefied Natural Gas (LNG) Reception and Regasification facility and associated Gas-Fired Power Station is to be designed and constructed at Acajutla, El Salvador. Part of the project included the construction of a new jetty, safety systems, utilities and services for an LNG Floating Storage Unit (FSU) and LNG Carriers (LNGC). The FSU will be berthed at a Jetty, supplying LNG to the onshore buffer tank.

Total had a problem at their Immingham refinery with contaminants in the Liquid Petroleum Gas (LPG) product stream. A plant was required that could remove these using absorbents to improve the quality of the stream to increase its value.
The project ran from feasibility to end of feed, with full front-end design, cost assessment and HAZOP assessment being completed.

BP required an offshore produced water treatment facility for one of their Southern North Sea platforms. A gas well connected to this platform cannot flow as it has significantly high water content and cannot be treated at the onshore terminal.
