157(1)Where the owner of a ship incurs liability under section 153 by reason of a discharge or escape which has occurred without his actual fault or privity then—
(a)he may limit that liability in accordance with the provisions of this Chapter, and
(b)if he does so, his liability (that is to say, the aggregate of his liabilities under section 153 resulting from the discharge or escape) shall not exceed 133 special drawing rights for each ton of the ship’s tonnage nor (where that tonnage would result in a greater amount) 14 million special drawing rights.
(2)For the purposes of this section the tonnage of a ship shall be ascertained as follows—
(a)where the registered tonnage of the ship has been or can be ascertained in accordance with the tonnage regulations, the ship’s tonnage shall be the registered tonnage of the ship as so ascertained but without making any deduction required by those regulations of any tonnage allowance for propelling machinery space;
(b)where the ship is of a description with respect to which no provision is for the time being made by the tonnage regulations, the tonnage of the ship shall be taken to be 40 per cent of the weight (expressed in tons of 2,240 lbs) of oil which the ship is capable of carrying;
(c)where the tonnage of the ship cannot be ascertained in accordance with either paragraph (a) or paragraph (b) above, a surveyor of ships shall, if so directed by the court, certify what, on the evidence specified in the direction, would in his opinion be the tonnage of the ship as ascertained in accordance with paragraph (a), or (as the case may be) paragraph (b), above if the ship could be duly measured for the purpose; and the tonnage stated in his certificate shall be taken to be the tonnage of the ship.
158(1)Where the owner of a ship has or is alleged to have incurred a liability under section 153 he may apply to the court for the limitation of that liability to an amount determined in accordance with section 157.
(2)If on such an application the court finds that the applicant has incurred such a liability and is entitled to limit it, the court shall, after determining the limit of the liability and directing payment into the court of the amount of that limit,—
(a)determine the amounts that would, apart from the limit, be due in respect of the liability to the several persons making claims in the proceedings; and
(b)direct the distribution of the amount paid into court (or, as the case may be, so much of it as does not exceed the liability) among those persons in proportion to their claims, subject to subsections (7) to (10) below.
(3)A payment into court of the amount of a limit determined in pursuance of this section shall be made in sterling in accordance with subsection (4) below.
(4)For the purpose of converting such an amount from special drawing rights into sterling one special drawing right shall be treated as equal to such a sum in sterling as the International Monetary Fund have fixed as being the equivalent of one special drawing right for—
(a)the day on which the determination is made, or
(b)if no sum has been so fixed for that day, the last day before that day for which a sum has been so fixed.
(5)A certificate given by or on behalf of the Treasury stating—
(a)that a particular sum in sterling has been fixed by the International Monetary Fund for the day on which the determination was made; or
(b)that no sum has been so fixed for that day and that a particular sum in sterling has been so fixed for a day which is the last day for which a sum has been so fixed before the day on which the determination was made,
shall be conclusive evidence of those matters for the purposes of this Chapter.
(6)A document purporting to be such a certificate shall, in any proceedings, be received in evidence and, unless the contrary is proved, be deemed to be such a certificate.
(7)No claim shall be admitted in proceedings under this section unless it is made within such time as the court may direct or such further time as the court may allow.
(8)Where any sum has been paid in or towards satisfaction of any claim in respect of the damage or cost to which the liability extends,—
(a)by the owner or the person referred to in section 165 as “the insurer”; or
(b)by a person who has or is alleged to have incurred a liability, otherwise than under section 153, for the damage or cost and who is entitled to limit his liability in connection with the ship by virtue of section 185 or 186;
the person who paid the sum shall, to the extent of that sum, be in the same position with respect to any distribution made in proceedings under this section as the person to whom it was paid would have been.
(9)Where the person who incurred the liability has voluntarily made any reasonable sacrifice or taken any other reasonable measures to prevent or reduce damage to which the liability extends or might have extended he shall be in the same position with respect to any distribution made in proceedings under this section as if he had a claim in respect of the liability equal to the cost of the sacrifice or other measures.
(10)The court may, if it thinks fit, postpone the distribution of such part of the amount to be distributed as it deems appropriate having regard to any claims that may later be established before a court of any country outside the United Kingdom.
159(1)Where the court has found that a person who has incurred a liability under section 153 is entitled to limit that liability to any amount and he has paid into court a sum not less than that amount—
(a)the court shall order the release of any ship or other property arrested in connection with a claim in respect of that liability or any security given to prevent or obtain release from such an arrest; and
(b)no judgment or decree for any such claim shall be enforced, except so far as it is for costs (or, in Scotland, expenses);
if the sum paid into court, or such part thereof as corresponds to the claim, will be actually available to the claimant or would have been available to him if the proper steps in the proceedings under section 158 had been taken.
(2)In the application of this section to Scotland, any reference (however expressed) to release from arrest shall be construed as a reference to the recall of an arrestment.
160Where, as a result of any discharge or escape of persistent oil from a ship, the owner of the ship incurs a liability under section 153 and any other person incurs a liability, otherwise than under that section, for any such damage or cost as is mentioned in subsection (1) of that section then, if—
(a)the owner has been found, in proceedings under section 158 to be entitled to limit his liability to any amount and has paid into court a sum not less than that amount; and
(b)the other person is entitled to limit his liability in connection with the ship by virtue of section 185 or 186;
no proceedings shall be taken against the other person in respect of his liability, and if any such proceedings were commenced before the owner paid the sum into court, no further steps shall be taken in the proceedings except in relation to costs.
161Where the events resulting in the liability of any person under section 153 also resulted in a corresponding liability under the law of another Liability Convention country sections 159 and 160 shall apply as if the references to sections 153 and 158 included references to the corresponding provisions of that law and the references to sums paid into court included references to any sums secured under those provisions in respect of the liability.
162No action to enforce a claim in respect of a liability incurred under section 153 or 154 shall be entertained by any court in the United Kingdom unless the action is commenced not later than three years after the claim arose nor later than six years after the occurrence or first of the occurrences resulting in the discharge or escape by reason of which the liability was incurred.
