LNG EXPORT PRE-FEED

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.

JETTY OPTION SELECTION STUDY

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.

RATIONALISING GAS PRODUCTION INFRASTRUCTURE

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.

HP LOADING ARM AND METERING SYSTEM FEED

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.

LOPA ASSESSMENT

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.

LNG REGASIFICATION CONCEPTUAL DESIGN

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.

PROCESS CONTROL OPTIMISATION

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.

LNG FLSO VESSEL AND ONSHORE TERMINAL FEED STUDY

OSL were commissioned to provide part of a FEED design for the Lavaca Bay LNG project, in Port Lavaca, situated between Galveston and Corpus. This consisted of one permanently moored FLSO with multiple connections to the onshore natural gas grid in South Texas. The designs needed to incorporate the potential for expansion and the addition of a second FLSO over time for a total production capacity of up to 8 MTPA.

LPG CONTAMINANTS FEED STUDY

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.

LNG TERMINAL DESIGN

IM Skaugen (IMS) already used their smaller Multigas Ships for Liquid Petroleum Gas (LPG) and wanted to also enter the Liquified Natural Gas business (LNG).
An opportunity for IMS arose when the Bahrain national oil company Bapco required a small land-based LNG storage facility sited on reclaimed land. The IMS philosophy to minimise land storage was to locate a storage ship offshore and then LNG could then be shuttled between the two.

ONSHORE TERMINAL OPTIMISATION

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.

OFFSHORE MARINE TERMINAL AND ASSOCIATED ONSHORE RECEIVING FACILITIES DESIGN

The Aguirre Offshore GasPort Project was designed to provide an offshore marine terminal and associated Onshore Receiving Facility (ORF) to support the continuous offshore re-gasification of liquefied natural gas (LNG) for onward delivery to onshore delivery points.

METHANOL INJECTION MODIFICATION CONCEPTUAL DESIGN STUDY

Wingas Storage UK Ltd. (WSUK) own and operate the Saltfleetby Natural Gas facility near Louth in Lincolnshire. The gas from Saltfleetby is fed via pipeline to the nearby Theddlethorpe Gas Terminal, operated by ConocoPhillips, where the gas is combined with gas from offshore gas fields, processed and fed into the National Transmission System.

MARINE DEVELOPMENT CONCEPTUAL DESIGN STUDY

To meet new International Maritime Organisation rulings being introduced from 2012, vessels travelling within 200 nautical miles of shore will need to cut their fuel sulphur content by 98%.
OSL were engaged to develop new technology that can be fitted to existing ships and vessels to meet the new regulations.

LNG BROWNFIELD MODIFICATION

OSL were requested by the largest independent Oil and Gas Company in Nigeria to develop a viable technical solution for a large (7600t) LPG receiving, storage and loading facility on a brown field site on the outskirts of Lagos.
The study was completed in less than 6 months with a multidiscipline project team based in the UK and Nigeria. Close contact was kept with the client in Nigeria to ensure that client’s requirements and expectations were met.
