EFC: KEY TO COLUMN HEADINGS AND ABBREVIATIONS
(Note: The four EFC tables contain identical data, except that the Builder and Design tables lack the Contr_Note column and the Contract table lacks the Note column. In addition, the order of fields varies, with EFC hull number coming first in the Hull table, Builder in the Builder table, Contract 1 and 2 in the Contract table, and Design in the Design table.)
Ehull1 [thru] Ehull2. EFC hull numbers of ships in contract. If "0", the contract contained no new ships but consisted solely of an adjustment to an earlier contract or contracts (contract table only) or the record is for a design to which no ships were ordered (design table only).
Qty. Number of new ships in the contract. For contracts that consisted solely of adjustments to earlier contracts (contract table only), this is the number of ships covered by the adjustments.
Design. EFC design number. For a list of EFC designs with their basic characteristics see the separate page, "List of EFC Designs with Descriptions." In the Note column, design numbers are preceded by the letter T (T1006).
Matl. Material used in hull construction: Wood, Composite (mixed steel and wood construction), Concrete, or Steel.
Type. Type of ship: barge, cargo, tanker, transport, seagoing tug (abbreviated as AT), or harbor tug (YT). "Hull" means a cargo ship contracted for without engines.
Builder. Name of the shipbuilder. The last name used by the builder during the WWI period is used here. The entry "DESIGN NOT ORDERED" (design table only) means that the purpose of the line is to represent a design that was not ordered. The entry "ZZ: NOT ASSIGNED" means that hull numbers were not assigned and the intended design is unknown.
City, State. Location of the shipbuilder (city and state).
Bhull1 [thru] Bhull2. Shipbuilder's hull numbers. The EFC recorded these for steel ships only.
Contr1 [thru] Contr2. EFC contract numbers. All 532 EFC ship construction contracts are accounted for in the contract table (which includes adjustments). The following abbreviations occur in Contr2: SUPP. = supplement to earlier contract, OPTION = option taken up under earlier contract, and NO # = contract without contract number. Some EFC contract numbers had suffixes (not shown in this list) indicating the types of ships covered: SC = all steel construction, WBC = wood barges, WH = wood hulls (without engines), WC = other wood construction, CC = composite.
Order. Contract date (YYMMDD). Example: 180605 = 5 June 1918.
Cx. Type of action in Canc. column. (Canc. = cancellation).
Canc. Cancellation date (YYMMDD) for the entire contract or for the portion of the contract covering the indicated hulls.
Note. (This column is not in the Contract table.)Some dates in this column are in the format "m.yy" (9.18 = September 1918). AP = transport. BLDR# = builder's hull number. CANC = cancelled. CONTR = contract. DSN = design. DELIV = delivered. FAB = fabricated. MOD = modified. NOT ABS = not found in the ABS register for 1920 (checked for tugs only). NUMBERS REUSED = EFC hull numbers reused from earlier order. PASS & CARGO = passenger and cargo. PURCH BLDG = purchased by the EFC while under construction. REFRIG = refrigerated. REQ = requisitioned ships (a few were added to the EFC building program after being requisitioned). REORD = reordered. STD = standard. SUBCONTR = subcontracted. T1006 = Design (type) 1006. T1015R = Design 1015, refrigerated variant. TO BLDR = hulls signed over to builder during cancellation process. TO PASS & CARGO = ordered built as P&C instead of AP. TO BETH WILMINGTON = contract transferred to Bethlehem Wilmington from Bethlehem Elizabethport, followed by Wilmington builder's hull numbers.
Contr. Note (Contract and hull tables only). This column contains modifications to contracts. It includes contract adjustments (new contract numbers and dates without changing the number of ships: ADJUSTED TO and ADJUSTED AS mean the same thing). It also includes consolidations of contracts: TO CONTRACT 477 indicates that ships ordered under the contract in the Contr and Order columns were transferred on the date given to a later contract, in this example 477, under which more ships had been ordered from the same builder, and the original contract was cancelled. COMPLETED UNDER CONTRACT DATED 200420 indicates the ships were completed under a contract dated 20 April 1920 that was not in this contract series. EFF. = effective.
DWT (Design table only). Deadweight tonnage.
LOA (Design table only). Length overall.
Notes (Design table only). T1006 = Design (type) 1006. 3500T = 3,500 tons. CONCRETE DSN #2 = Concrete Design Number 2. Designs 1057 came in two official variants, 1057A and 1057B. (Design 1117 also apparently came in two variants).
