Shipbuilder: Astilleros Espanoles

Ship Name: Sirius I

Ship Type: Product Carrier

Owner/Operator: Tomasos Brothers

The first oil product carrier designed and built in Europe according to Lloyd's Register (LR) ShipRight procedures was recently delivered. Sirius I is a 46,500-dwt, double- hulled oil/product carrier built for non-restricted service in world traffic.

It is powered by a 6S50 MC MAN B&W diesel engine rated 11,640 bhp at 127 rpm.

This arrangement enables a speed of 14.8 knots, fully loaded at 90 percent MCR.

Built by Astilleros Espanoles for Tomasos Brothers, the vessel measures 182.5 m over- all, with a 17.3-m depth, and a 12.3-m scantling draft. Flying the Bahamian flag, the ship is owned by Emerald Star Shipping.

Eight cargo tanks, plus two slop tanks give a total capacity of 53,200-cu.-m. Every cargo and slop tank has its own submerged pump, permitting the cargo to be unloaded in 15 hours. Cargo and slop tanks are coated with a phenolic coating scheme, allowing the ship to carry clean products such as MTBE and pentane.

Sirius I has obtained notation SDA, FDA and CM of LR. ShipRight procedures guar- antee that standards of safety, quality and reliability are applied during the design, con- struction and operating life of a ship's hull. ShipRight comprises eight procedures and the notations it carries in the Register of Ships are proof of both owner and builder com- mitment to the ongoing care and safety of the ship.

Structural Design Assessment (SDA) is a detailed analysis of a ship's structural response to applied static and dynamic loadings. This mandatory procedure enables the derivation of an optimum distribution of material, and also an appropriate level of scantlings in both primary and secondary structures. It is applied, in addition to the normal plan approval requirement, to the structural arrangement of all new oil tankers over 190 m, and to other ships where the ship type, size and structural configuration demand it.

Fatigue Design Assessment (FDA) is supported by an enhanced direct calculation methodology using several data, i.e. sheer against the reversals to failure, supplement- ed with large scale models of actual ship structural details. In using FDA, a ship designer or plan approval surveyor can reportedly easily modify the scantlings and arrangements in order to improve the fatigue life.

Construction Monitoring (CM) is to ensure that all recommendations and specifica- tions arising from the SDA and FDA procedures are consolidated and implemented dur- ing construction. It is undertaken in addition to the usual surveying tasks carried out during construction and comprises careful controls on the alignment, fit-up and weld- ing of the structural details identified as critical.

Ship Name: SG Prosperity

Ship Type: Bulk Carrier

Owner/Operator: Ever Fortune Ltd./

Shougang Concord International

Daewoo Heavy Industries Ltd delivered the 211,320-dwt bulk car- rier SG Prosperity to Sougang Concord International Transport Ltd. on September 21, 1996. There are two sisterships which are cur- rently under construction. SG Prosperity contains nine cargo holds which are strengthed for heavy cargoes and grab discharge. The holds are suitable for loading pattern where Nos. 2, 4, 6 and 8 may be empty, and mainly carrying coal and iron ore.

Five pairs of water ballast tanks interconnected between top side and bottom tanks divided at center line by duct keel are arranged.

The portion of high-tensile steel used in construction is approxi- mately 69 percent, with hold frames thickened as per IACS unified requirement with mild steel, and protection within the holds (exclud- ing tank top) comprising two coats of 250 micron bleached tar epoxy. Main propulsion power is provided by a Hanjung B&W 7S70MC main engine with MCR of 23,950 bhp at 81.5 rpm, and

NCR of 20,360 bhp at 77.2 rpm (85 percent MCR), which provides a service speed of 14.5 knots. Electrical power is derived from three sets of 680-kW diesel alternators, and steam is supplied from a 2,500 kg/h oil fired auxiliary boiled and a 1,600 kg/h exhaust gas economizer. A Nor- control bridge con- trol system, JRC satellite navigation system and two radars are installed in front center of the wheelhouse. The computer supplied by MECA handles loading cal- culation. A f i v e -t i e r deckhouse provides accomoda- tions for a complement of 29 per- sons.
