16 Years Loss Adjusting Experience; 4 Years Middle East

Oil and Gas Geothermal Wells Downstream Oil and Gas production Pipelines Energy Generation and Transmission Industrial Gas Turbines Industrial Processing Plant Mining and Smelting Infrastructure Works Construction and Civil Works

OIL AND GAS

Fixed platform and mobile drilling rigs

Well ‘kick’ problems leading to cratering

Production casing failure

Oil-gas separators, oil tanks, gas compression

stations, treating plants, pump stations and

gasoline-sulphur recovery plant

Dry drilling problems on an offshore rig damaged the drill bit, loss under deductible.

DOWNSTREAM OIL AND GAS Refining

The accidental loss of steam caused heat damage to a hydrogen reformer, property loss $7,400,000. Business interruption losses were less than the time deductible.

DOWNSTREAM OIL AND GAS LPG production Mobil process – natural gas to

methanol and then to gasoline (synfuel)

Cause investigation: A weld failed fracturing a heat exchanger pipe and caused an explosion in a waste heat recovery unit at a LNG facility, EAR loss in excess of $100,000,000.

GEOTHERMAL Geothermal well risks

Geothermal power generation

Five sections of a production casing failed at a depth of 876m during quenching of a geothermal well, loss $15,000,000 and generation losses $4,000,000. It was suggested that the well was at the end of its economic life and the claim was eventually withdrawn.

DOWNSTREAM PETROCHEMICAL PLANT Steam cracking and catalytic reforming of

refinery hydrocarbons for the production of olefins (ethylene and propylene) and aromatics (benzene and xylene isomers)

Plastics, resins, fibres, solvents and detergent production

Fertiliser manufacture

Faulty design led to the failure of the concrete structural members supporting plant and equipment at a fertiliser plant; quantum was in excess of $350,000,000 and the claim was repudiated. Ewan Cresswell of Integra Technical Services was appointed by facultative reinsurers to mentor the handling of this claim.

PIPELINES Gas and oil pipelines Potable and wastewater

reticulation (and processing risks)

A flood collapsed a bridge supporting a natural gas pipeline. Due to the lead time to reconstruct the bridge the pipeline was reinstated under the riverbed. The initial claim of circa $9,000,000 for the pipeline was negotiated at $4,600,000.

ENERGY GENERATION AND TRANSMISSION

Natural gas, light fuel oil, and biogas simple cycle and co-generation facilities

Reservoir and run of river hydropower Steam turbines and associated

desalination plant Diesel and coal fired power stations Alternative renewable energy –

geothermal and wind generation Power transmission equipment

The design of the HPC (high pressure compressor) stage 17 on an ABB GT26 gas turbine was defective, and as a consequence a stage 17 blade cracked during the gas turbine running-in procedure, EAR loss $2,900,000. (DSU claimed $16,000,000 but subsequently negotiated to nil).

INDUSTRIAL GAS TURBINES Industrial single and dual shaft

gas turbines Aero turbines

The vane ring, which is part of the diffuser assembly on the high pressure turbine stub shaft, suffered a high cycle fatigue failure causing an explosion inside the hot section sump area of a GE LM6000 gas turbine, machinery breakdown loss $9,000,000 and business interruption losses mitigated to nil.

The combustion systemand first stage nozzle ofthe HPT appeared to bein reasonable condition,similar to what had beenseen during the routineborescope conducted onthe 25 May 2002.

Bearing 4R appearedto be in poorcondition, with debrisand foreign objectsvisible close to thebearing.

The blades on the firststage of the HPC have mid-span retainers. Theretainer seen appearedbent.

There appeared to bea bend in the firststage of the HPCblade seen.

The HPC outletguide vanesappearednormal.

There was no sign ofsignificant foreignobject damage at anypoint along the rotatingplant before the firststage of the HPT.

All blades of the firststage of the HPT haddisintegrated. Therewas evidence ofsevere over -temperature in thisarea.

All blades andvanesdownstreamof the firststage of theHPT wereobliterated.

The seal between the first stagenozzle and first stage disc, andblades of the HPT was gone andmolten metal had made its wayinto the area between the nozzleblock and the disc.

Material had becomelodged between the firststage nozzle and disc ofthe HPT.

Drain lines (LPrecoup) from theB-C sump areahad ruptured.

It appears that there hasbeen an explosion andsevere over temperaturein this area with moltenmetal and missingpipework (presumablydisintegrated in theviolent environment), anddebris throughout.

Bearing 4Bappeared to be inreasonablecondition.

Bearing 5Rshowedevidence ofhaving beenburnt.

Impact damageto the struts inthe exhaustcasingpresumablycaused by bladeand vanematerialsexiting the unit.

There wasevidence of bladerubbing on theHPC outercasing.

The two severe areasof damage were in theHPT and LPTdownstream of thefirst stage nozzle ofthe HPT and the B-Csump.

INDUSTRIAL PROCESSING PLANT Chemical process manufacturing Automated manufacturing Food processing (in particular

the dairy industry) Water and wastewater

treatment plants Pulp and paper Pollution and contamination

incidents

A lump of milk powder oxidised causing an explosion in a vibrofluidiser that set fire to a milk powder dryer. Property damage and business interruption losses $20,000,000. My role in this loss was relatively minor, but it was my first loss adjusting assignment (1993) and I’m very grateful to the team of adjusters that were kind enough to share their knowledge and experience.

MINING AND SMELTING Open cast and continuous

coal mining Aluminium and iron (steel)

smelting

A screening machine caught fire inside a coal mine, plant loss $350,000. Prompt emergency fire fighting prevented a much more serious fire from occurring.

A flashover inside a rectifier transformer shut down the number five pot line at an aluminium smelter, property loss $500,000. Business interruption losses were uninsured.

INFRASTRUCTURE WORKS Water treatment Wastewater treatment

Nocardia rod bacteria caused extreme foaming of the activated sludge (human effluent) inside the digesters of a wastewater treatment plant resulting in a series of ongoing losses to plant and equipment totaling $1,850,000.

A contractor left construction debris inside pipework, which during the maintenance period damaged the membrane filters used in the second stage of a water treatment plant, CAR loss $3,500,000.

Resorts and hotels Multistory tower blocks and

high rise construction Civil infrastructure works

including culverts, rock revetments and coffer dams

Roads, bridges and under passes

Airports Tunnels

CAR fire loss in a hotel $30,000,000
