AMSTERDAM, Jan 24 (Reuters) - Dutch maritime oil and gas engineer SBM Offshore said a dispute with a client would lead to "a significant additional adverse impact" on its 2011 results, and that its chief financial officer would quit, driving shares down 7.5 percent.
The world's largest supplier of floating production, storage and offloading (FPSO) platforms had already shocked investors in July with the announcement of a $450 million impairment charge, which resulted in a first-half operating loss and led to a shake-up at the top when its chief executive stepped down.
The charge resulted from a row with two clients, Canadian group Encana, which is working on the Deep Panuke gas project off the coast of Nova Scotia, and Talisman Energy , which is developing the Yme oilfield, offshore Norway.
As recently as Nov. 17, SBM Offshore gave an upbeat outlook for the sector in its third-quarter trading update, reiterating it expected to break even in the full year after taking the impairment charge, and to see a 5 percent increase in sales.
But SBM Offshore, which is due to report 2011 results on March 2, warned on Tuesday it was facing increased challenges with the hook-up and commissioning of the Yme Mopustor platform.
"Continuing intransigence and unreasonable client demands, which are being aggressively resisted, are contributing significantly to the very low productivity and increased scope of work, all of which are the subject of arbitration proceedings with the client," it said in a statement.
"This is further exacerbated by continuing bad weather."
SBM Offshore said it would give details of the revised financial impact as soon as feasible, but that it was expected to lead to a significant additional adverse impact on the 2011 results. The eventual outcome is dependent upon resolution of ongoing disputes with the client, it added.
The cost overruns could reach $250 million to $350 million on top of the $450 milllion already announced, Rabobank said in a research note.
Mopustor "is turning into the mother of all setbacks," analyst Michael Roeg of KBC Securities said in a research note.
With the departure of the CFO close on the heels of former CEO Tony Mace, Roeg added, the Mopustor units "now claim their second victim ... The damage to SBM's risk profile could be more sizable, counterbalancing the positive impact from solid trends in the bread-and-butter FPSO business."
SBM Offshore said chief financial officer Mark Miles would step down in May, but gave no reason.
Former chief executive Tony Mace resigned last year following the surprise impairment and was replaced by chief operating officer Bruno Chabas with effect from this month.
"I cannot recall such a huge write-off being taken on a single project, and it only seems to get worse," Jos Versteeg, analyst at Theodoor Gilissen, said, although he added that the outlook for SBM's other businesses was still rosy.
"Most pain related to the write-offs is over now, and I see a lot of FPSO possibilities in Australia and Brazil on the horizon."
